SaferBirths Bundle of Care (SBBC) is a package of innovative clinical and training tools coupled with low-dose high-frequency simulation-based on-job training guided by local data. This bundle is implemented in 30 health facilities in Tanzania to improve birth outcomes. 21 Focus group discussions and 43 individual interviews were conducted. In total, 94 midwives and 12 doctors were involved. The results point to the relevance of SBBC in addressing maternal and perinatal deaths, the good quality and modality of training, and development of a culture that enhances learning from mistakes. A well-accepted intervention, such as SBBC, has a huge potential for bringing the intended impact in health provision.
